Programming Projects

Description

There will be 4 programming projects: 1 on socket programming, 2 on TCP, and 1 on routing. We will post details according to the published schedule. For each project we will hold a tutorial session during the lab time slot.

For 4 KENS programming projects, students have to build up their own TCP implementation on top of KENS (KAIST Educational Network Simulator) framework. We provide a minimal user-level function interface that interacts with user applications and an emulated IP layer which performs static routing. The underlying emulator can simulate both reliable and unreliable link states with configurable and reproducible packet losses and reordering. Your task is to implement the TCP stack API.

  • Project 1: Echo server and client on KENS
  • Project 2: KENS part I, II
  • Project 3: KENS part III
  • Project 4: TBA
